Video Transcript for Review of SmartPlug Marine Power - Power Cord - SM73VR

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this four foot long SmartPlug marine power cord. Has the 50 amp male SmartPlug on this end and the 50 amp female twist lock connector on the other end. Now, this cord will let you connect your boat to shore power with using the SmartPlug system connector. On this end, we have the 50 amp female twist lock connector that'll plug into your 50 amp male twist type inlet on your boat.

And on this end is the 50 amp male SmartPlug connector that'll plug into a 50 amp female SmartPlug at your dock side. Want to zoom in so you can see a close up on these connectors. We'll snark, start using the SmartPlug system right here. You can see this will ensure a nice, solid connection. You can see it has a nice sleeve design that will keep the weight and the tension off of your electrical pins.

And the body of the plug is what will bear the weight to keep the points of electrical contact secure. You can see it is a straight-in connection with SmartPlug male end, makes plugging in very easy even when it's dark out. They do use triple weatherproof seals to help prevent water corrosion and overheating. And the construction on this SmartPlug is all the external metals are a marine-grade, 316 stainless steel, the electrical pins are a nickel-plated brass, and all the plastics they use are UV and heat resistant. On the other end is your standard, female twist lock connector.

It offers a nice, secure twist lock connection. It is a black cord. And this part is made in the USA. The length again on this is four feet. The amperage is 50 amps.

The voltage is 125 and 250 volts. But that should do it for the review on the four foot long SmartPlug marine power cord with the 50 amp male SmartPlug to the 50 amp female twist lock connector..

Arrived well fits well. I use when rv is on driveway. Etrailer price and shipping went well.



by:

Excellent quality and it reduces dependance on the 50A cord for routine low power needs. retrained has an aewesome inventory of parts and accessories for all trailering needs. Great customer service and follow-up on my order.



by:

Haven’t had a chance to install parts yet but after watching YouTube seems like an easy project. Like the improved design over the factory plug. Fast delivery, quicker than anticipated…etrailer always comes through



by:

Diane's follow up was excellent! I definitely recommend etrailer.



by:

Perfect fit. Works as needed.



by:

The SmartPlug is a great innovation, far better and more secure than the old style, twist connectors, and safer for your RV or boat. This new pigtail makes it even easier to switch to the SmartPlug since now there is no need to cut the end of a perfectly good shore power cord in order to adapt to this superior system. Plus you add 4 feet to the length of your cord. This is the second boat I have converted to the SmartPlug system.



by:

Switched out 2020 Airstream Classic to the SmartPlug system, and needed a way to provide power to charge the batteries and operate the lights and fans, while in storage. The 50 to 15 AMP adapter is well made, with all connections being cast, eliminating any possibility of weather intrusion.
As ususal Teri N is awesome to deal with, trailer is hard to be for customers service.



by:

Exactly as described. We'll made.



by:

Came quickly and is good quality.



by:

Outstanding customer service!

Great customer service and awesome prod uct.

This item was originally ordered last summer but was out-of-stock in the inventory and was on back order. Multiple times the manufacturer established a delivery date that then a few days before the delivery date postponed delivery and re-established a new delivery date. etrailer kept me informed via email whenever they received new information from the manufacturer.

etrailer emailed me as soon as they received the item into its inventory, told me when it would be shipped and met their shipping date. The item came on time and I immediately used it to charge my camper van. It is exactly as advertised and I am totally satisfied with it.



by:

Product worked great and Etrailer had it in stock!



by:

I haven’t had a chance to use the product yet therefore I can’t comment on it. But etrailer customer service was great and the sale price was the best I see anywhere. I received the product promptly and well packed for shipping.



by:

by:

by:

Well made, very expensive!



by:

This is an excellent product that continues to serve me well!



by:

Everyone I spoke to was very knowledgeable, They knew me and what I had ordered. They all spoke good English. Also the product was first class. I wish more people were that way.



by:

Exactly what I needed



by:

Couldn’t find this product in stock on any other web site. Initially ordered from [online] but they cancelled the order because product was back ordered. etrailer had this in stock and very quickly delivered it. Previously ordered heavy duty trailer hitch from eTrailer. Great products, fast delivery and excellent customer service.



by:

I was hesitant in ordering this pigtail since it was so expensive compared to the actual extension cord it self or other pigtails from other brands. Once I had received it and saw how great quality this product is, I was reassured to myself in not having buyers remorse. Thanks Smartplug for building such a great product.
